Účinnost protismykových úprav na cementobetonových a asfaltových vozovkách

Abstract

The aim of the Bachelor thesis was to produce a reshuffle on the topic of anti-skid adjustments of stiff and rigid roadways. In the second part, an analysis was made of skid adjustments in the city of Ostrava. The analysis was carried out on selected sections where the accident rate before and after the application of the skid adjustment and its condition were examined. Accident rates dropped on four of the five sections studied. So we can consider skid adjustments as effective. The condition was assessed in two as non-compliant out of the need for local or entire correction of the security anti-skid adjustment. In the next section, the work deals with the technology of using recycled aggregates for anti-skid treatment of concrete and asphalt pavement surface. The mean depth of the surface macrotexture using the measuring method and the coefficient of friction found by the pendulum were detected. The values of the desired macrotexture depth exceed the requirement by almost twice. The values of the coefficient of friction exceed the required values by 10 %. Recycled aggregates are therefore suitable for anti-skid treatment.
